“Here Dr. Sacks recounts the case histories of patients lost in the bizarre, apparently inescapable world of neurological disorders: people afflicted with fantastic perceptual and intellectual aberrations; patients who have lost their memories and with them the greater part of their pasts; who are no longer able to recognize people and common objects; who are stricken with violent tics and grimaces or who shout involuntary obscenities; whose limbs have become alien; who have been dismissed as retarded yet are gifted with uncanny artistic or mathematical talents.”
